Cover panel of a box blank



FIG. 1 is a top perspective view of a cover panel of a box blank showing my new design, the broken line showing of the adjacent appended components is for illustrative purposes only and forms no part of the claimed design;

FIG. 2 is a top plan view of the cover panel; the bottom view being identical.

FIG. 3 is a front elevation view of the cover panel;

FIG. 4 is a right side elevation view of the cover panel;

FIG. 5 is a left side elevation view of the cover panel; and,

FIG. 6 is a rear elevation view of the cover panel.

My cover panel is characterized by opposing front and rear edges and opposing left and right side edges, with the left and right side edges being non-parallel and converging toward one another as they extend from front to rear, except for a section at the rear end of each of the left and right side edges where the edge swings outwardly in a convex arc and intersects an end of the rear edge. 

I claim the ornamental design for a cover panel of a box blank, as shown and described.
